Title: Pipe joint for joining high corrosion resistant stainless steel-titanium and manufacture thereof
Inventor: SASADA YASUHIRO
IPC: F16L13/02
Filed: 1988-10-12
Abstract: PURPOSE:To obtain a pipe joint for joining high corrosion resistant stainless steel to Ti by forming Ta as a joint medium for first and second tubular members and forming alloys of the tubular members and the joint medium at prescribed intervals in the joint medium of the interface between the first tubular member and the joint medium. CONSTITUTION:A Ta plate of the joint medium 2 is subjected to explosive joining to a low C stainless steel plate of base metal 1 and alloy Ti plates 3 are subjected to explosive joining thereon. Further, the two Ti plates thicker than the first layer Ti plate are subjected to explosive joining in order. At the time of explosive joining of the Ti plates 3 of the second and subsequent layers, heat treatment to soften the joining interface between the Ti plates and the stainless steel plate which are subjected to explosive joining is carried out. The above-mentioned heat treatment is carried out at the temperature in which Ta and stainless steel are not diffused mutually substantially and in addition, in Ar where Ti and Ta are not oxidized. The heat treatment is carried out when every explosive joining is finished.

Title: Optical reader
Inventor: HARANO TETSUO
IPC: G06K9/20
Filed: 1984-11-30
Abstract: PURPOSE:To read a picture at a constant speed by providing x-set of light emitting side fibers transmitting the light from x-set of light emitting elements to x-set read points on paper and x-set photodetector side fibers transmitting the reflected light to a photodetector. CONSTITUTION:When a CPU30 outputs a drive signal and a drive motor 12 is turned, a read head is reciprocated. After the moving speed of the read head reaches a constant speed, when a read timing pulse is inputted to the CPU30, the 1st read section Di1 of each set is opposed to plural spots Si at the same time. In this case the CPU30 lights selectively the light emitting element Li1 opposed to each read section Di1 via a light emitting element drive circuit 35 at the same time. The light from each light emitting element Li1 is irradiated to each spot Si on paper through the light emitting side fiber Ti1, the reflected light is made incident at the same time on plural photodetectors Pi through each photodetector side fiber Ri1. Every time each read section crosses the read point, the picture on paper is read, then the read speed is quickened.

IPC: B01D63/00
Filed: 1990-09-25
Abstract: PURPOSE:To prevent the leakage of a potting solution by perfectly bringing a stepped protruding part and a projection to a close contact state by pressing the projection provided to the inner periphery of an adapter in a state running on the outer periphery of the stepped protruding part to the end surface of the stepped protruding part by the fastening force of a fastening frame. CONSTITUTION:When a fastening frame 14 is fitted in an adapter 7 from the outer periphery thereof, the adapter 7 is fastened from the outside and the projection 12 of the adapter 7 is pressed to the end surface of a stepped protruding part 5 by this fastening force and the fitting surface of the opening part 6 of the adapter 7 and that of the inner periphery of a case opening part 4 come into close contact with each other in a liquidtight state. A potting solution is injected in the hermetically closed space formed between the adapter 7, the case opening part 4 and the terminals of hollow fibers 2 to fill the same. At this time, inner pressure is applied to the peripheral wall 8 of the adapter 7 but, since the outside thereof is reinforced by the fastening frame 14, the peripheral wait 8 does not protrude. Further, the fitting surfaces 13 of the case 3 and the adapter 7 are perfectly sealed by the projection 12 pressed to the end surface of the stepped protruding part 5 to prevent the leakage of the potting solution.

Title: Altitude detector for airframe
Inventor: OKUDA TORU
IPC: F42B15/01
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To detect the altitude of an airframe using a signal available from an ordinarily mounted instrument without use of a large-sized expensive altimeter by detecting a target direction, evaluating a flying distance for a predetermined time, and estimating the altitude from the target direction and the flying distance. SOLUTION: An output signal of an angle detector 3 includes error of an attitude angle so that a bias correction circuit 8 corrects a preset attitude angle and estimates a target angle 9 (θ1 , θ2 ), and stores it in a memory circuit 10. A writ/read control circuit 12 reads a signal from the memory circuit 10 based upon a signal from a timer 7, and sends target angles at two different times to an altitude estimation circuit 11. Simultaneously, an integration circuit 13 integrates a flying speed previously set in a speed set circuit 14 with a time difference between two different times available from the timer 7 and estimates a flying distance L16 and sends it to the altitude estimation circuit 11. The altitude estimation circuit 11 estimates the altitude H15 using the formula.

Abstract: PURPOSE: To surely discharge static electricity between first and second connectors by causing a discharge of the static electricity to a chassis and earth via a conductive frame before the other conductive parts of the connectors are coupled together, if the front end of each spring arm of a clip is engaged with the front end of an alignment post. CONSTITUTION: The pair or spring arms 122 of a grounding clip 120 project forward and inward toward the central axis of an alignment post receiving hole 100, and their free ends are smoothly engaged with the front end of an alignment post 80 and deflected accompanying with the engagement. During an alignment process, the grounding clip 120 is engaged with the alignment post 80 before connectors 22, 18 are coupled together and before either of their parts are physically engaged or the conductive part of one connector most approaches the terminal part of the other. The grounding clip 120 is conductively connected to the shield 40 of the connector 22 at a position behind connector coupling faces, the alignment post 80 is conductively connected to the shield 44 of the connector 18, and the shield 44 is conductively connected to a chassis and earth.  Thus when first physical engagement of the spring arms 122 with the alignment post 80 occurs, static electricity is surely discharged prior to subsequent engagement of the connectors 18, 22.

Title: Combustion apparatus
Inventor: ONO TADASHI
IPC: F23D14/34
Filed: 1988-10-11
Abstract: PURPOSE:To achieve a reduction in noise and a maximum of combustion in amount is available and to stabilize the combustion irrespective of combustion using a premix or diffused combustion by providing in the center inside a cylindrical combustion chamber with a tubular tapering reducing in size a nozzle-flame hole device in combination for fuel and an axial-flow blower approximately concentrically and with the nozzle-flame hole device in a position facing the tubular tapering reducing in size. CONSTITUTION:A spiral flow of air for combustion, which flows downstream toward a tubular tapering part 2 reducing in size while it encircles a nozzle-flame hole device 4, forms a negative-pressure region at the periphery of the nozzle-flame hole device 4. On the other hand, pressurized fuel, fed through a proportional valve 5 and a fuel pipe 6, is ejected from the nozzle-flame hole device 4 toward a tubular tapering part 2 reducing in size downstream. The spiral flow of air and the fuel, as a result of their collision, form a flame-staying region downstream from the nozzle-flame hole device 4. Thus part of the fuel and part of the air are supplied to the flame-staying region and, for the rest, diffusion and mixing at high speeds are promoted with the fuel drawn into the spiral flow of air as they flow downstream. After ignition by means of an igniting device which operates after the start of a blower 3, a flame is sustained at the flame-staying region downstream from the nozzle-flame hole device 4 so that a stabilized long spiral flame can be formed.
